Did you know that there has never been a recorded perfect bracket for the NCAA basketball championship tournament? That may have to do with the fact that there are over 9 quintillion possible brackets! In this exploration, students are guided to first determine the number of games played in the tournament. Then they use pattern recognition to cacluate the number of outcomes possible for the tournament. A follow-up scenario asks students to find the amount of time it will take a class of 20 stud

Students discover pi by measuring the circumferences and diameters of circular objects and then find their ratios. Students organize their work in the table. The best part -- a tape measure is provided on the worksheet! Students can review the definitions of diameter and circumference in the graphic at the beginning of the worksheet. After finding the ratio, students complete fill-in-the-blank statements to solidify what they have learned. Then they can apply the ratio to solve problems invol

Why do we use 3.14 for pi? It all started with Archimedes over 2200 years ago. In this exploration perfect for pi day, students follow along as Archimedes sandwiched a circle with a diameter of 1 between two hexagons to find a lower and upper bound of pi. Students complete various part of the process, such as calculating perimeters and writing inequalities for the lower and upper bounds of pi. After learning the process, students complete a fill-in-the-blank summary using a word bank. The explo
